My dad has had the idea that he wants to convert his 03 Chevy Silverado 3500 Dually crew cab Duramax to a 6 door. The reason for this is he used to have a Suburban and he doesn't really want to have a Suburban and his truck. It would take away his 8 foot bed and make it a 6 foot and then there would be 6 doors and 3 rows of seats. He uses his truck probably 3 times a week just for towing, but it is also his everyday vehicle so he wants to get a nice used 1500 for everyday use and leave this one is the garage more (it already has 70,000 miles. Him and I have both seen multiple trucks like this but we can't seem to find anyplace that will do it (they say they would have to build 2 of them to crash test one)
Does anyone know some places that will do it, preferably around PA?
